Evaluating left atrial pressure (LAP) solely from the left ventricular preload perspective is a restrained approach. Accurate assessment of LAP is particularly relevant when pulmonary congestion and/or right heart dysfunction are present since it is the pressure most closely related to pulmonary venous pressure and thus pulmonary haemodynamic load. Amalgamation of LAP measurement into assessment of the ‘transpulmonary circuit’ may have a particular role in differentiating cardiac failure phenotypes in critical care. Most of the literature in this area involves cardiology patients, and gaps of knowledge in application to the bedside of the critically ill patient remain significant. Explored in this review is an overview of left atrial physiology, invasive and non-invasive methods of LAP measurement and their potential clinical application.

重症监护中左心房压力的床边评估：一个多方面的宝石

仅从左心室前负荷的角度评估左心房压力 (LAP) 是一种受限的方法。当存在肺充血和/或右心功能不全时，准确评估 LAP 尤其重要，因为它是与肺静脉压和肺血流动力学负荷最密切相关的压力。将 LAP 测量合并到“跨肺循环”评估中可能在区分重症监护中的心力衰竭表型方面具有特殊作用。该领域的大部分文献都涉及心脏病患者，而将知识应用于危重患者床边的知识差距仍然很大。本综述探讨了左心房生理学、LAP 测量的侵入性和非侵入性方法及其潜在临床应用的概述。
